Abstract

L'invention concerne une couche intermédiaire ainsi que du verre feuilleté présentant les fonctions de base indispensables au verre feuilleté, telles que la transparence, la résistance aux intempéries, la résistance à l'adhésion et à la pénétration ainsi qu'un blanchiment réduit de la périphérie du verre même en atmosphère hautement humide. La couche intermédiaire est préparée à partir d'un film en résine d'acétal de polyvinyle plastifié, et lorsqu'elle a une épaisseur comprise entre 0,3 et 0,8 mm et qu'elle est immergée dans de l'eau à 23 °C , elle présente une valeur de diffusion de 50 % ou moins après 24 heures.
